LIGHT-FIXTURE.

Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed June 23, 1915. Serial No. 85,772.

To all whom it may concern Be it known that I, WILLIAM D. HERWIG, Jr., a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Light-Fixtures, of which the following is a specification.

The present invention has reference particularly to light fixtures of that general type which is best suited to the accommodation of incandescent bulbs or globes. The fixture may also be used with great advan tage in connection with incandescent mantels of those types which are in general use, so that certain features of the construction are well adapted for use in connection with gas burners. I will state, however, that the drawings illustrate the features of invention as applied to a fixture for electric light service, inasmuch as the features of the invention are particularly well adapted for this.

class of service.

One of the objects of the invention is to provide a sectional fixture of such construction that the various elements or sections can he used for the building u of fixtures of different sizes and forms. T is object of the invention may otherwise be stated to be the provision of a construction such that two or more styles of fixture may be obtained by assembling the standard parts in the proper manners.

Another object of the invention is to provide a fixture of such construction that it will ventilate in such a manner as to permit outwardly flowing currents of air. These currents of air will serve to cool the incandescent globe or bulb, in case the fixture be used for the accommodation of an electric light lobe, or will supply the gas burner with t e necessary air in case the fixture be used in connection with a gas burner.

Another object of the invention is to so construct the several fixture sections that the completed fixture will effectively shed rain or other moisture without permitting the entrance of the same into the body of the fixture. This is a very important feature particularly in fixtures intended for the accommodation of incandescent bulbs for the reason that water falling or dripping on the hot bulb will often crack or disrupt the same.

Other objects and uses will appear from a detailed description of the invention which consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawings: Figure 1 shows a side elevation of the completed fixture, the same being provided with a globe and a reflector; Fig. 2 is a section taken on the line 22 of Fig. 4 looking in the direction of the arrows; Fig. 3 is a section taken on the line 3-3 of Fig. 4 looking in the direction of the arrows; Fig. 4 is a vertical section through the assembled fixture, the socket for the incandescent lamp being broken away and the reflector and globe also being broken away; Fig. 5 shows a vertical section through the upper portion of the assembled fixture, being a section taken at right angles to the section shown in Fig. 4; and Fig. 6 is a fragmentary section through a portion of the fixture showing the reflector attached directly to the intermediate section.

In Figs. 1 and 4 the fixture is shown as built up from the cap 7, the sleeve 8, and the shade holding ring 9. The cap is preferabl dished in form, having the downwardy depending rim or flange 10. At various polnts around the periphery of this rim there are spaced the inwardly projecting lugs 11, shown in Figs. 2 and 4. Upstanding from the central portion of the cap is the hollow post 12. The upper end of this post carries an inlet fixture 13 which may be of any desired construction. In the construction illustrated it comprises the flange 14 threaded onto the upper end of the post, and onto which is seated the member 15. The sides 16 of this member rest squarely down against the arms 17 of the flange, being secured to said arms in any desired manner, whereas the sides 18 of the member 15 project beyond the flange. Between the flange and member '15 is seated the insulatlng bushing 19. The electric wires 20 and 21 pass up through openings in the lower side of the bushing and then turn downwardly and run down through the hollow post to a point within. the mterior of the cap 7. Within this cap is secured the electric light socket 22. This socket is conveniently lllustrated as being built up from the members 23 and 24. The member 23 is permanently con nected to the cap, whereas the member 24 may be removably connected to the member 23. The wires pass downward centrally through the member 23 and are connected to terminal posts therein, which in turn connect to the proper portions of the socket 24 for the delivery of current tothe bulb. I do not illustrate the socket in detail for the reason that the same may be one of any number of types of construction well known on the market.

The sleeve 8 has its upper end notched to provide a series of openings 25, as best shown in Fig. 4. Screws 26 are extended through the lugs 11 and are threaded into the side portions of the section 8 so as to hold the same in place. On account of the presence of the lugs 11 there is left a circular opening between the cap 7 and sleeve 8, the lower end of which opening communicates with the outside atmosphere. The upper end of this opening communicates with the interior of the fixture by way of the notches 25.

The lower portion of the sleeve is flared outwardly to provide the flange 27. The under face of this flange has a plurality of downwardly facing lugs 28. The shade holding ring 9 has its upper portion inturned to provide the flange 29 which seats up against the lugs 28, whereas its lower portion is flared outwardly and then turned down to provide the peripheral lip 30. The size of the upper portion of the shade holding ring is such as to leave a circular opening between the flange 27 and the upper portion of said ring, as shown in Figs. 3 and 4. The flange 29 is secured to the lugs 28 in any desired manner as by means of the screws 31.

The lower flanged portion 30 of the shade holding ring is provided with the lugs 32 against which may be seated a reflector 33 when it is desired to use such reflector. The upper portion of this reflector is of such size as to leave a circular opening between it and the flanged portion 30 of the shade holding ring except at those points on said flange where the lugs 32 are located. Thumb screws 34 may be extended through the flanged portion 30, and preferably through the lugs thereof for the purpose of clamplng in position the globe 35. This globe will ordinarily be used in outdoor service, for the purpose of keeping rain and other moisture off from the incandescent bulb.

When a lobe is used in this class of service it is or i linarily provided with a bottom opening or perforation through which cool ing air may enter the bulb for circulation around and into contact with the bulb. This air will pass upwardly into the shade holding ring. A portion of it may thence circulate outward through the circular opening at that time, and another portion may continue on up to the point where the sleeve and the shade holding ring are joined together. At this point an additional quantity of air may circulate out into the atmosphere, or may continue on up to the polnt of junction between the cap and sleeve. At such point of junction it may find exit to the outside air. It thus appears that the cooling air may leave the fixture at either or all of the three locations enumerated, thus insuring a very perfect and satisfactory ventilation and cooling of the bulb at all times. Nevertheless on account of the relative relationships existing between the adjacent upper and lower portions of the consecutive sections rain or other moisture will be effectively shed and will not gain access to the interior of the fixture.

Referring to Fig. 6 I have therein illustrated the reflector 36 as being attached directly to the lugs 28 of the sleeve. In this case the shade holding ring has been dispensed with, and consequently a fixture of smaller overall dimensions is secured. This arrangement would be desirable for use in connection with interior lighting where the globe 35 is dispensed with. It will be observed, nevertheless, even when using the combination shown in Fig. (3 the fixture will ventilate between the reflector and the sleeve as well as between the sleeve and cap.

While I have herein shown and described only one general form of construction embodying the features of my invention, still it will be understood that I do not limit myself to the same except as I may do so in the claims.
